DESCRIPTION
These devices consist of two independent low
voltage comparators designed specifically to oper-
ate from a single supply over a wide range of volt-
ages. Operation from split power supplies is also
possible.
These comparators also have a unique character-
istic in that the input common-mode voltage range
includes ground even though operated from a sin-
gle power supply voltage.
All the pins are protected against electrostatic dis-
charge up to 2kV. As a consequence, the input
voltages must not exceed the magnitude of Vcc+
or Vcc-.

The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the
output, so no loading charge exists on the reference of input lines.

Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the
comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V bellow the negative power supply, if
used).
